I was wondering if anyone out there has any references to line clipping for
lines which are wider than one pixel.  Actually, the lines may be made from
brushes derived from a 16x16 bit pattern.  You may have seen similar brushes
in paint programs like MacPaint.  What I'm wondering is how to do the clipping
fast.  I can generate a separate 1-bit wide line for each pixel in the brush,
and clip each line separately, but this is too slow.  Any help would be
appreciated.
